In a recent after school class, students used their basic electrical concepts to build a Squishy Circuit. This particular circuit required students to build small cubes of conductive dough, bridging them between insulating layers of dough. As the circuit grew, so did voltage. Students bridged each cube of conductive dough with a galvanized nail and copper wire, jumping over the non-conductive slices. A meter was used to measure the slowly increasing voltage.
